Signs an unsigned Pact command.

Field	Description	Type - Optional
blockchainKind	Kadena	String
kind	PactCommand	String
command	The Pact command JSON serialized as string.	String

• The response only includes the signature. You must package it correctly before submitting the transaction to chain.

• Kadena does not have a deterministic serialized format. The exact serialized string used for signing must be submitted.

Typescript Example with kadena.js

import {
  Pact,
  readKeyset,
} from '@kadena/client'

const walletId = 'wa-6lbfv-9esgj-88s80c0qsih0a393'
const wallet = await dfnsClient.wallets.getWallet({ walletId })

const myAddress = wallet.address
const myPubKey = wallet.address.split(':')[1]
const toAddress = 'k:b7a3c12dc0c8c748ab07525b701122b88bd78f600c76342d27f25e5f92444cde'
const toPubKey = toAddress.split(':')[1]

// 1 KDA
const pactAmount = { decimal: '1.0' }

// coin contract
const contract = 'coin'

const transferCommand = Pact.builder
  .execution(
    (Pact.modules as any)[contract as 'coin']['transfer-create'](
      senderWallet.address, recipient, readKeyset('ks'), pactAmount)
     )
    .addSigner(myPubKey, (withCapability: any) => [
      withCapability('coin.GAS'),
      withCapability(`${contract as 'coin'}.TRANSFER`, myAddress, toAddress, pactAmount),
    ])
    // add public key of recipient here
    .addKeyset('ks', 'keys-all', toPubKey)
    // set the network Id for the transaction. For testnet use 'testnet04', for mainnet use 'mainnet01'
    .setNetworkId('testnet04')
    // here we set the chainId of the chain we want to broadcast to
    .setMeta({ chainId: '0', senderAccount: myAddress })
    .createTransaction()

const res = await dfnsClient.wallets.generateSignature({
  walletId,
  body: {
    kind: 'PactCommand',
    command: transferCommand.cmd,
  },
})
